Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Apple-butter Custabd Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
In a bowl, beat together the eggs, apple butter, sugar, allspice, sweet milk, and salt.
Pour the mixture into the pie crust.
Bake
Bake in the preheated oven until set, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving the filling its structure.
- Apple butter
- Adds concentrated apple flavor and sweetness to the custard.
- Sugar
- Sweetens the custard and contributes to its tender texture.
- Sweet milk
- Provides the liquid base that the eggs set into a smooth custard.
The step that matters
Bake until set. Eggs set as their proteins coagulate with heat. Pulling the pie too early leaves a runny centre, while overbaking can make the custard grainy or cracked.
Swap the allspice
How well each one fits the dish's main ingredients (egg, apple, butter, sugar, milk):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits better
- Allspicethe original
Fit is the average pairing score against egg, apple, butter, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
